In this case we actually consider speed (Messerschmit) vs. manoeuvrability (Gloster Meteor).If we recall battles of manoeuvrable but low-speed aircrafts (for example, pre-war fighters) against new high-speed fighters, we will see the first had chances, especially in case of a more or less skilled pilot.So, in the battle Gloster vs. Me 262, Gloster (it was rather perfect machine) had significant chances.But, it should be noted, Me 262 had good opportunities to dodge a battle.Somehow or other, I stake on Gloster Meteor.
